摘要: 目的 评价血浆1,3-β-D-葡聚糖检测(G试验)对恶性血液病患者侵袭性真菌感染(IFD)的诊断价值。 方法 对220例血液恶性肿瘤患者进行回顾性分析。以中国IFD工作组制定的《血液病/恶性肿瘤患者侵袭性真菌感染的诊断标准与治疗原则》为对照标准,研究血浆1,3-β-D- 葡聚糖浓度单个指标在诊断IFD时受试者工作特征(ROC)曲线下面积、敏感性、特异性和诊断所需时间。 结果 相比于金标准,血浆1,3-β-D-葡聚糖浓度单个指标诊断恶性血液病患者IFD的ROC曲线下面积、敏感性、特异性和诊断所需时间分别为0.946 1、98.6%、83.0%和(3.86±2.92)d。 结论 G试验诊断恶性血液病患者IFD较传统诊断方法在敏感性及所需时间上均有较大优势,且有较好的阴性预测值,能帮助早期诊断和排除IFD,提高临床诊治效果和减轻患者医疗负担。

Abstract: Objective To evaluate the significance of plasma 1,3-beta-D-glucan assay(G test)for the diagnosis of invasive fungal diseases(IFD)in patients with malignant hematological diseases. Methods A retrospective analysis was performed in 220 inpatients with malignant hematological trmor.According to Diagnostic Criteria and Principles of Treatment of Invasive Fungal Infections in Patients with Blood Diseases/Malignancies as gold standard,the plasma 1,3-beta-D-glucan concentration′s area under the receiver operating characteristic(ROC)curve,sensitivity,specificity and time to diagnosis in the diagnosis of IFD were analyzed. Results Comparing the gold standard,the plasma 1,3-beta-D-glucan concentration′s area under the ROC curve,sensitivity,specificity and time to diagnosis were 0.946 1,98.6%,83.0% and(3.86±2.92)d,respectively. Conclusions G test has good sensitivity and time to diagnosis for the diagnosis of IFD in patients with malignant hematological diseases,and has a good negative predictive value in early diagnosis and exclusion of IFD. It can improve the efficiency and reduce the care burden of patient.
